Abstract

The present invention discloses a warehouse logistics handling system using a non-powered self-propelled transport vehicle, which includes a frame, a non-powered self-propelled drive unit and a lifting and rotating platform. The opening on the top of the frame includes a guide and a push-button assembly, and a plurality of rotating wheels are centrally arranged on the frame. The lifting and rotating platform includes a platform, a driving rod and a locking and releasing assembly. One end of the driving rod is pivoted to the platform, and the end thereof passes through a through hole and is rotatably connected to a power input end. The driving rod is provided with a guide structure. The locking and releasing assembly is used to prevent the platform from pivoting relative to the driving rod. When the platform carries an object and has a downward pressure, it is driven by the downward pressure to slide downward from the first position of the guide structure through the guide member to the second position, so that the platform follows the driving rod to move downward and rotate relative to the frame, and the platform is driven by the driving rod. The unit converts the downward pressure of gravity into forward kinetic energy and stores energy, and drives multiple wheels forward. When the frame reaches the target position, the locking release assembly is released by the push-pull assembly, so that the platform can pivot relative to the driving rod, and the items on the platform can be tipped out, so that the potential energy of the load of the items can be converted into the kinetic energy of the displacement of the self-propelled vehicle, and combined with the platform lifting and rotation and tilting locking release functions, the purpose of simple transportation and auxiliary transportation of items in a small transfer transportation space can be achieved.

Description

Warehousing logistics handling system using non-powered self-propelled transport vehicles

The present invention relates to a warehouse logistics transportation system using a non-powered self-propelled transport vehicle, in particular, a warehouse logistics transportation technology that converts the load potential energy of items into the kinetic energy of vehicle displacement and combines the functions of platform lifting, rotation, tilting, locking and releasing to achieve simple transportation and assist in the transportation of items in a small transfer transportation space. The present invention can be used in a warehouse logistics transportation system to achieve the purpose of short-distance transportation between short workstations, and greatly save the cost of electricity or fuel through a cyclical process; another feature is that it uses the two major principles of energy conservation of gravitational potential energy converted into kinetic energy and elastic potential energy and momentum conservation of mass and speed converted into rotation to form the entire process of carrying, walking, unloading, and cyclical round trip.

The so-called reciprocating self-propelled vehicle refers to a self-propelled power transmission mechanism designed without electric power and directly using physical principles such as gravity, elasticity, levers or mechanics. Generally speaking, the more common application method is to use the self-propelled power transmission mechanism as a self-propelled unmanned transport vehicle; or as a self-propelled power source for a self-propelled lifting platform to compensate for the automated transportation system; or in areas where the automated warehousing system fails to cover the blind spots of the transported items. Although it is known that non-electrically driven self-propelled vehicles have the advantage of self-propelled functions and do not require electricity consumption, their kinetic energy storage mechanisms are mostly implemented using a spiral spring mechanism, which requires a large number of components and is complex, resulting in a higher manufacturing cost.

In order to improve the above deficiencies, the applicant has applied for the following patent cases:

1. Invention Announcement No. I705916 "Karakuli Unpowered Load-carrying Reciprocating Self-propelled Vehicle", which includes a frame, a lifting platform, a toggle-type linkage mechanism, an energy storage reciprocating traction mechanism and a wheel mechanism. The lifting platform is arranged on the frame so as to be movable up and down. When the platform bears the weight of the object, the lifting platform moves downward relative to the frame, and drives the toggle-type linkage mechanism to accumulate kinetic energy and drive the wheel mechanism on the frame to move forward a certain distance in one direction. When the object is removed and there is no downward pressure of gravity, the toggle-type linkage mechanism releases the accumulated kinetic energy and drives the lifting platform to move upward relative to the frame, thereby driving the wheel mechanism on the frame to move forward a certain distance in the opposite direction, so that the Karakul function can be realized by the construction of the toggle-type linkage and the energy-accumulating reciprocating traction mechanism, and then the self-propelled vehicle can be driven to move back and forth a certain distance through the mechanical accumulated kinetic energy generated by the elastic stretching recovery. Although the patent has the function of unpowered self-propelled, it does not have the function of lifting, rotating, tilting, locking and releasing the platform, so that the lifting, rotating, tilting and other functions of the platform cannot be realized, making it impossible to achieve the purpose of simple transportation and assisting the transportation of items in a small transfer transportation space.

2. Invention Announcement No. I732711, "Lever-type non-powered load-bearing reciprocating self-propelled vehicle", includes a vehicle frame, a lifting platform, a swinging mechanism, a storage-release reciprocating traction mechanism and a rotating wheel mechanism. The lifting platform is arranged on the vehicle frame so as to be movable up and down. When the platform bears the weight of the object, the lifting platform moves downward relative to the vehicle frame, and drives the swinging mechanism to link the storage-release reciprocating traction mechanism to accumulate kinetic energy, so as to drive the rotating wheel mechanism to move forward a certain distance in one direction. When the object is removed and there is no downward pressure, the swinging mechanism links the storage-release reciprocating traction mechanism to release the accumulated kinetic energy and drive the lifting platform to move upward relative to the vehicle frame, thereby driving the rotating wheel mechanism on the vehicle frame to move forward a certain distance in the opposite direction. Although the patent has the function of unpowered self-propelled, it also does not have the function of lifting, rotating, tilting, locking and releasing the platform, so that the lifting, rotating, tilting and other functions of the platform cannot be realized, making it impossible to achieve the purpose of simple transportation and assisting the transportation of items in a small transfer transportation space.

In view of this, the above-mentioned self-driving car technology and the aforementioned patents are indeed not perfect and still need to be improved. In addition, based on the urgent needs of the relevant industries, the inventors of the present invention have finally developed a set of inventions that are different from the above-mentioned knowledge technologies and the aforementioned patents after continuous efforts in research and development.

The first purpose of the present invention is to provide a non-powered self-propelled transport vehicle mechanism, which mainly converts the potential energy of the load into the kinetic energy of the self-propelled vehicle displacement, and combines the functions of the lifting, rotating, tilting, locking and releasing of the platform. In addition to the functions of the lifting, rotating and tilting of the platform, it can also achieve the purpose of assisting the transportation of items in a simple and small transfer space. The technical means to achieve the above-mentioned first purpose include a frame, a non-powered self-propelled drive unit and a lifting and rotating platform. The opening on the top of the frame includes a guide and a push-pull assembly, and a plurality of rotating wheels are arranged on the frame. The lifting and rotating platform includes a platform, a driving rod and a locking and releasing assembly. One end of the driving rod is pivoted to the platform, and the end thereof passes through a through hole and is rotatably connected to a power input end. The driving rod is provided with a guide structure. The locking and releasing assembly is used to prevent the platform from pivoting relative to the driving rod. When the platform carries an object and has a downward pressure, it is driven by the downward pressure to slide downward from the first position of the guide structure through the guide. The guide reaches the second position, so that the platform follows the driving rod to move downward and rotate relative to the frame. The unpowered self-propelled drive unit converts the downward pressure gravity into forward kinetic energy and stores energy, and drives multiple wheels forward. When the frame reaches the target position, the locking release assembly is released by the push-button assembly, so that the platform can pivot relative to the driving rod, and the items on the platform can be tipped out.

The second purpose of the present invention is to provide a storage logistics handling system using a non-powered self-propelled transport vehicle mechanism, which mainly matches the non-powered self-propelled transport vehicle mechanism with a matching storage handling and transporting device, thereby achieving the purpose of assisting the handling of items in a simple handling or small conversion handling space in the storage system. The technical means for achieving the above-mentioned first purpose include a frame, a non-powered self-propelled drive unit and a lifting and rotating platform. The opening at the top of the frame includes a guide and a push-pull assembly, and a plurality of rotating wheels are installed on the frame. The lifting and rotating platform includes a platform, a driving rod and a locking and releasing assembly. One end of the driving rod is pivoted to the platform, and the end thereof passes through a through hole and is rotatably connected to a power input end. The driving rod is provided with a guide structure. The locking and releasing assembly is used to prevent the platform from pivoting relative to the driving rod. When the platform carries an object and has a downward pressure, it is driven by the downward pressure to slide downward from the first position of the guide structure through the guide. The guide piece reaches the second position, so that the platform follows the driving rod to move down and rotate relative to the frame. The unpowered self-propelled driving unit converts the downward pressure gravity into forward kinetic energy and stores energy, and drives multiple wheels forward. When the frame reaches the target position, the locking release assembly is released by the toggle assembly, so that the platform can rotate relative to the driving rod, thereby allowing the items on the platform to be tipped out. The invention comprises a plurality of the non-powered self-propelled transport vehicle mechanisms and a storage and transportation system, wherein the storage and transportation system comprises a plurality of first object loading and moving mechanisms and a plurality of second object loading and moving mechanisms, wherein the plurality of first object loading and moving mechanisms are sequentially located at the origin position of each of the non-powered self-propelled transport vehicle mechanisms, and the plurality of second object loading and moving mechanisms are sequentially located at the target position of each of the non-powered self-propelled transport vehicle mechanisms; when each of the non-powered self-propelled transport vehicle mechanisms is respectively located at the origin position, the plurality of first object loading and moving mechanisms place the at least one object into the corresponding non-powered self-propelled transport vehicle mechanism. On the platform of the transport mechanism, when the platform bears the weight of the at least one item and has the downward pressure, the unpowered self-propelled transport mechanism is driven by the downward pressure to move forward to the target position, so that the at least one item on the platform is tilted onto a container of the second item loading and transferring mechanism after rotating the angle, and then the at least one item is carried out by the second item loading and transferring mechanism; when the platform does not have the downward pressure, the unpowered self-propelled transport mechanism generates restoring kinetic energy, and uses the restoring kinetic energy to drive the unpowered self-propelled transport mechanism back to the original position.

In order to allow the Honorable Review Committee to further understand the overall technical features of the present invention and the technical means for achieving the purpose of the present invention, a specific embodiment is provided with accompanying drawings for detailed description:

Please refer to FIGS. 1 to 13 , which show a first embodiment of the first aspect of the present invention, comprising a frame 10, a lifting and rotating platform 20, and a non-powered self-propelled driving unit 30. A through hole 11 is formed near the center of the top of the frame 10, and a guide member 12 and a push-pull assembly 13 are sequentially protruded upward from the periphery of the through hole 11, and a plurality of rotating wheels 330 are pivotally arranged at the bottom of the frame 10. The lifting and rotating platform 20 is installed on the frame 10 in a lifting and rotating manner, and includes a carrier 21, a driving rod 22 and a locking release assembly 23. The carrier 21 is used to carry the object 40. One end of the driving rod 22 can be rotatably connected to the carrier 21. The end of the driving rod 22 passes through the through hole 11 and can be rotatably connected to the power output of the non-powered self-propelled drive unit 30. The driving rod 22 has a guide structure 220 extending axially from the outer periphery thereof for the guide member 12 to be inserted and slidably provided. The locking and releasing assembly 23 is provided near the pivotal position between the driving rod 22 and the carrier 21, so that the carrier 21 is locked by the locking and releasing assembly 23 and cannot pivot relative to the driving rod 22. When the carrier 21 carries the weight of the article 40 and has a downward pressure, The driving rod 22 is driven by the downward pressure gravity and slides downward from the first position d1 of the self-guiding structure 220 through the guide member 12 to the second position d2, so that the platform 21 moves downward and rotates relative to the frame 10 following the driving rod 22, and the unpowered self-propelled driving unit 30 converts the downward pressure gravity transmitted by the driving rod 22 into forward kinetic energy and stores energy, and The forward kinetic energy drives the multiple rotating wheels 330 forward. When the frame 10 reaches the target position, the guide member 12 is exactly located at the second position d2, and the locking release member 23 is driven by the locking assembly 13, so that the locking release member 23 is in a released state, so that the platform 21 can pivot relative to the driving rod 22, and the object 40 on the platform 21 can be dumped out.

This embodiment is an operation embodiment based on the first embodiment. When the product on the platform 21 is tilted out without downward gravity, the unpowered self-propelled driving unit 30 releases the stored energy to generate restoring kinetic energy, and uses the restoring kinetic energy to drive the plurality of wheels 330 backward. When the frame 10 reaches the origin position, the guide member 12 is exactly at the first position d1. The driving rod 22 is driven to slide upward from the second position d2 of the guide structure 220 through the guide member 12 to the first position d1, so that the platform 21 follows the driving rod 22 to rotate in the opposite direction and move upward relative to the frame 10, and the push-pull assembly 13 is disengaged from the locking and releasing assembly 23, so that the locking and releasing assembly 23 is in a locked state, thereby locking and preventing the platform 21 from pivoting relative to the driving rod 22.

Please refer to Figures 2 to 4, which are the first specific embodiment based on the first embodiment. This embodiment mainly defines the specific structure of the guide structure 220. The guide structure 220 includes a straight section groove 220a extending downward from the second position d2 and a spiral section groove 220b connected to the end of the straight section groove 220a and rotating a preset angle to the first position d1. The preset angle can be one of 90 degrees or 180 degrees; that is, the carrier 21 can be rotated 90 degrees or 180 degrees to achieve the purpose of turning at a specific angle.

Please refer to FIGS. 1 to 8, which are a second specific embodiment based on the first embodiment. This embodiment mainly defines the specific components and action principle of the locking and releasing assembly 23. The locking and releasing assembly 23 includes a fixing seat 230, two locking cams 231 and two torsion springs 232 disposed at one end of the driving rod 22. The bottom of the carrier 21 is provided with a hinge. The pivot 210 is provided with a pivot shaft passing therethrough and is pivotally connected with one end of the driving rod 22. The two locking cams 231 are respectively passed through the shaft and are pivotally connected in the slots 230a of the two side walls of the fixing base 230. The two torsion springs 232 are respectively sleeved on the shaft and abut the slots 230a of the fixing base 230 with one end and abut the two locking cams 231 with the other end, so that the two locking cams 231 generates a rotational elastic force relative to the fixed seat 230. When the guide member 12 is located at the second position d2 of the guide structure 220, the push-pull assembly 13 compresses the rotational elastic force of the two torsion springs 232 and pushes the two locking cams 231 to rotate in one direction, so that the carrier 21 can pivot relative to the driving rod 22. As shown in FIG. 6, the pivot seat 210 will not press the two locking cams 231, so It can pivot; when the push-pull assembly 13 is disengaged from the two locking cams 231, the two torsion springs 232 generate a restoring rotational elastic force to push the two locking cams 231 to rotate in the opposite direction, so that the carrier 21 is blocked by the two locking cams 231 and cannot pivot relative to the driving rod 22. As shown in FIG5, the pivot 210 will press the two locking cams 231, so it cannot pivot. In addition, the fixed seat 230 is provided with a first slot 230c and a second slot 230b for the driving rod 22 to pass through. When the guide member 12 is located at the second position d2 of the guide structure 220, the second slot 230b can be used for the guide member 12 to pass through, as shown in FIG6.

This embodiment mainly defines the specific structure of the guide member 12 and the push-pull assembly 13. The guide member 12 is a latch protruding toward the through hole 11, and the push-pull assembly 13 is two push rods arranged on both sides of the latch. A push rod 14 is protruding upward from the through hole 11 relative to the latch to provide a support function when the carrier 21 pivots relative to the driving rod 22.

Please refer to Figures 1 to 4, which are the fourth specific embodiment based on the first embodiment. This embodiment mainly defines the specific structure of the carrier 21, which is a shallow dish container with a slightly duckbill shape.

Please refer to FIGS. 1 to 4, which are the fifth specific embodiment based on the first embodiment.

The toggle mechanism 312 includes two connecting rods 312a. A first end of each of the two connecting rods 312a is pivoted to two ends of a pivot seat 313. A roller 312b is pivoted to a second end of each of the two connecting rods 312a. The end of the driving rod 22 is rotatably disposed at a position as a power input. The first guide rail 310 is provided on a pivot seat 313 at one end of the guide structure 220. A slider 313a is provided on one side of the pivot seat 313. The slider 313a is movably guided by the first guide rail 310. The roller 312b of the second connecting rod 312a is movably guided by at least one second guide rail 311. When the platform 21 carries the weight of at least one object 40 and has a downward pressure, the driving rod 22 moves from the first position d1 of the guide structure 220 to the second position d2. The platform 21 slides down through the guide member 12, and moves downward and rotates relative to the frame 10 following the driving rod 22. The driving rod 22 pushes the slider 313a of the toggle mechanism 312 to move downward along at least one first guide rail 310, thereby linking the second connecting rod 312a to move and rotate, so that the second end of the second connecting rod 312a and the roller 312b roll along at least one second guide rail 311 toward the driving rod 22. As shown in the figure, a positioning member 314 is provided below the pivot seat 313 to position the pivot seat 313 for rotation.

The at least one first sprocket 331 is wound around the chain 322. When the second end of the second connecting rod 312a rolls or moves toward the direction close to the driving rod 22, the second end of the second connecting rod 312a pulls the cable 320, and the cable 320 links the chain 322. The chain 322 drives the at least one first sprocket 331 to rotate forward and stretch the linear expansion spring 323 at the same time. On the one hand, the at least one first chain driven by the at least one first chain 331 is rotated forward. The wheel 331 drives the two coaxial wheels 330 to rotate so that the frame 10 moves forward, and on the other hand, the linear expansion spring 323 has a retraction force as a restoring kinetic energy; when at least one object 40 on the platform 21 is tilted and there is no downward gravity, the retraction force of the linear expansion spring 323 pulls back the chain 322 and drives at least one first sprocket 331 to rotate reversely while pulling back the cable 320. The cable 320 pulls back the second end of the second connecting rod 312a to drive the slider 313a to move up along at least one first guide rail 310 and drive the rod 22 and the platform 21 to move up and rotate in the opposite direction relative to the frame 10.

The object loading and transferring mechanism 2a places at least one object 40 on the platform 21 of the corresponding unpowered self-propelled transporter mechanism 1. When the platform 21 bears the weight of at least one object 40 and has a downward pressure, the unpowered self-propelled transporter mechanism 1 is driven by the downward pressure to move forward to the target position pb, so that at least one object 40 on the platform 21 is tilted onto a container of the second object loading and transferring mechanism 2b after rotating at an angle, and then the second object loading and transferring mechanism 2b carries at least one object 40 out; when there is no downward pressure on the platform 21, the unpowered self-propelled transporter mechanism 1 generates a restoring kinetic energy, and uses the restoring kinetic energy to drive the unpowered self-propelled transporter mechanism 1 back to the original position pa.
